running the ports at 1G on Trident-II is a no-no if there is egress pressure on the 1G ports. If the traffic bursts on the 1G port are predominantly ingress, then that may not be a major issue. Most organisations will have traffic profiles which are substantially more heavily loaded one way or the other, so this isn't as clear-cut as "don't ever do this". Monitoring egress drops is always a sensible thing to do. Also the trident chipset will only operate in cut-thru mode if all ports on the device are configured to be the same speed, which will impact on buffer utilisation. Nick
